For a display of British pomp and ceremony, watch the Changing the Guard ceremony outside Buckingham Palace.
Changing the Guard or Guard Mounting is the process involving a new guard exchanging duty with the old guard.
The Guard that looks after Buckingham Palace is called The Queen's Guard and is divided into two Detachments: the Buckingham Palace Detachment (responsible for guarding Buckingham Palace) and the St James's Palace Detachment (responsible for guarding St James's Palace).
All the guards taking part in the ceremony are dressed in traditional red tunics and bearskin hats, and the ceremony is set to music.
Changing the Guard also takes place at Windsor Castle and at Horse Guards Arch on Horse Guards Parade.
